Title: Circuit and method for generating filler pixels from the original pixels in a video stream
Inventor: ZHOU QINGGANG
IPC: H04N5/44
Filed: 1999-08-03
Granted: 2001-09-11
Abstract: In one aspect of the invention, an image processing circuit includes a processor that receives a value of a pixel of an original first video image and a value of a pixel of an original second video image. The processor generates a first pixel-value component from the value of the pixel of the first video image, and generates a second pixel -value component from the value of the pixel in the original second video image. From the first and second pixel-value components, the processor generates a value of an estimated pixel, and generates a revised first video image by combining the estimated pixel in the original first video image. One can use such an image processing circuit to generate a missing video field from an existing video field so as to generate frames of video from single fields of video. By implementing the described technique, such an image processing circuit is less likely to overlook significant interfield motion, and often uses significantly less memory than prior image processing circuits. In another aspect of the invention, the processor of the image processing circuit receives first and second sets of pixel values for first and second groups respectively of pixels in a video image. The processor generates direction values from the first and second sets of pixel values for an estimated pixel that is disposed in the video image between the first and second groups of pixels. The processor generates a value for the estimated pixel based on the direction values. One can use such an image processing circuit to generate the spatial-interpolation value of the pixels in a missing field from the pixels in an existing field to generate a video frame from a single video field. By implementing such a technique, the processor is much less likely to miss interpret a thin line as a directional edge, and thus is less likely to introduce related artifacts into the generated video frame.

Title: Method for measuring the sensitive electromotive force to verify the quality of rotator magnetization
Inventor: PAN YANN-GUANG
IPC: G01R31/34
Filed: 2000-06-27
Granted: 2002-05-21
Abstract: The present invention provides a method for measuring the sensitive electromotive force to verify the quality of rotator magnetization, which pre-manufactures a standard stator of a motor for use as a measurement standard, and further wound a set of sensitive coil on the standard stator, so that, when the rotator under test is combined with the standard stator and rotated by a driver, the sensitive coil can detect the anti-electromotive force signal generated by the rotator, thereby determining the quality of the rotator. Because the present measurement method is a closed circuit detection when the rotator is combined with the stator, the result is very close to the phenomenon of actual motor rotation, and the detection is convenient without encountering an axis aligning problem, thereby increasing the manufacturing efficiency of the manufacturing lines.
